After IV contrast administration, the median CT derived lung volume decreased mild by 1.1%, while median emphysema volume decreased by relevant 11%. This results in a decrease of median emphysema index by 9%. The median lung density (15th percentile) increased after contrast application by 18 ...
Hepatic CT enhancement: effect of the rate and volume of contrast medium injection in an animal model Background: To evaluate the relative effect of rate of injection and volume of contrast medium on aortic, portal, and hepatic enhancement during computed ... P Garcia,G Genin,PM Bret,... ...
To verify the technical feasibility of low contrast volume (40mL) run-off CT angiography (run-off CTA) with the individual scan time optimization based on double-level test bolus technique. A prospective study of 92 consecutive patients who underwent run-off CTA performed with 40mL of contrast ...
In addition to whole-brain segmentation, it now also performs Cortical parcellation, automated QC, and intracranial volume (ICV) estimation (see figure below). Also, most of these features are compatible with SynthSeg 1.0. (see table). 01...
6.Error Analysis of Contrast CT Scan on Contouring of Gross Tumor Volume in Three Dimensional Conformal Radiotherapy of Lung Cancer增强CT在肺癌适形放疗靶区勾画中的误差分析 7.The Study of Diagnosing Early-staged Lung Cancer by Dynamic Enhanced Computed Tomography Scanning;CT动态增强扫描诊断早期肺癌的...
Objective To summary the clinical role and value of care,and to prevent and disposal the adverse reactions of contrast agent in the process of enhanced CT scan.Methods From May 2003-May 2008,800 patients were randomly selected from the enhanced CT scan and nurses had to be effective prevention...
In addition, the second volume scan (V2) was automatically chosen using the predicted time-to-peak delay that was defined in Eq. 1. Hence, the prospective timing protocol simulation is summarized in Eqs. 2 and 3 as: [Math Processing Error]tV1=ttrigger+TD (2) [Math Processing Error]tV...
Axial non contrast CT scan (a) shows left basal ganglia hemorrhage and a round calcified lesion near it. The findings are high probable of underlying vascular lesion and showed to be an Arteriovenous malformation (AVM) in brain CTA (b). ...
We found that outpatients undergoing abdominal CT scan preferred water only as oral contrast above the positive oral contrast. This does not influence image quality. One observer experienced slightly less confidence in the evaluation of the GI tract, peritoneum, retroperitoneum and lymph nodes; this ...
(Equation 1)Ct(t)=Ktrans∫0tCp(τ).e−kep(t−τ).dτ+ve.Cp(τ) Here, Ctrepresents GBCA concentration in the tissue, Cprepresents the GBCA concentration in thearterial bloodplasma, Ktransis the transfer constant characterizing GBCA diffusion from the intravascular volume to EES, and kepis...
